A horseshoe-shaped valley, cut deep into the mountains, opens up into wide gorges.

Along these flow many water sources which feed the Soča River:- the Mlinarica, which thrusts water across almost impassable channels; - the Krajcarica, which does not lose its force when it disappears and then sources again in a multitude of springs; - the Vrsnik with its blue-green pools and - many other water sources which in rainy weather transform the valley into a fairy tale land of a hundred waters.

In Zadnja Trenta, the most remote part of the valley, in a basin, we can find Zapotok - a 180 m high steep rock face boasting the highest waterfall in the Triglav NationalPark.

The Soča River chisels its most remarkable troughs near the village of Soča where the Velika koritaare located. These are 750 m long and plunge to a depth of 15 m between the sides that are, in places, only 2 m apart.

A little higher up the Soča River carves out Mala Korita (small gorge), about 100 m long, up to 6 m deep and in places no more than 1 m wide.
